The oil engineers that have spoke on the subject of what oil we should have in our early cars were clear.
Detergent oil with additives.
Contrary to popular belief the detergent does not pull all the sludge into the oil. It may help clean up a worn engine and suddenly start noises.
The additives are critical in protecting you engine. The water that gets into the engine from condensation from sitting and not being warmed up to cook out will convert some chemicals into acids.
Also you do NOT need to change the oil every 500 miles. That was for the poor quality oil of 1930. You need to consider the type of driving, but cars run on the road are good for a couple of years and or a couple of thousand miles. No need to waste money or the environment. Plus really have you ever heard of an engine full of oil ever failing becuase the oil was old? You are highly unlikely to ever put enough miles on your car to make a difference.
